measuring volumes is a routine task for a laboratory. it is therefore all the

more important to ensure the long term quality of the instruments required

for this, from volumetric flasks through to stoppers. Day in day out, for

every analysis.

like all DURan® laboratory glassware, DURan® volumetric glassware

exhibits excellent thermal durability, it is practically inert and is characterised

by its extremely high thermal shock resistance. it is also highly cost effective

thanks to its distinctive anti-corrosion properties.

in short, DURan® volumetric glassware ensures that undesirable influences

are minimised as much as possible, therefore ensuring constantly high

precision with every measurement.

strict guidelines are followed in the selection of raw materials and batch

preparation for borosilicate glass 3.3. moreover, the excellent quality of

DURan® laboratory glassware is guaranteed by concentrating production

fully at the company's own locations. This is the case with every phase of

production – from glass melting through to calibration.

The result: the highest possible precision when it comes to measuring

volumes.

foR The highesT DemanDs: qUaliTy RighT Down The line

whether measuring liquid amounts, diluting solutions or mixing several components – DURan®

volumetric products, such as volumetric flasks, measuring and mixing cylinders to cover all applications.

Top quality process stability for all aspects of volume measurement can therefore be guaranteed in the

laboratory. high levels can be expected for all other laboratory activities that use DURan® laboratory

glassware.

The DURan® range of volumetric measurement products is characterised by an impressive array

of advantages in addition to the products being manufactured from the chemically highly resistant

borosilicate glass 3.3 that offers chemical, thermal and mechanical stability.

for example:

Unrestricted choice – The range of products on offer covers all accuracy classes including the

associated certifi cates and glass specifi cations

excellent print image − Emphasises the most important information, such as volume specifi cation,

accuracy class and standard ground joint details

clear labelling − Batch numbers are imprinted clearly on the glass, while individual numbers are

laser-etched onto the base of the volumetric fl ask

in addition, the range also includes new

ergonomically shaped stoppers for simple and

secure opening and closing (see page 23).

8 9pRecise DiffeRenTiaTion: The Two accURacy classes

Two accuracy classes "a" and "b" are essentially available for classifying the DURan® volumetric flasks,

measuring and mixing cylinders.

accuracy class "a":

indicates the accuracy limit in accordance with Din and iso and is therefore the highest accuracy class.

"a" apparatus bears the conformity symbol "h", which indicates that the requirements of the german

weights and measures regulations as well as the relevant standards are fulfilled.

Tolerance for a volumetric flask in accuracy class "A"

Tolerance for a volumetric flask in accuracy class "B"

accuracy class "b"

indicates an accuracy limit that is double that of class "a".

All glassware is heated in an oven following printing and the colour is fired on to the glass. This procedure

guarantees the high chemical and thermal resistance of the enamel print used, and therefore their

long life and economic efficiency. Important information, such as volume, accuracy class and the

schoTT DURan® logo, should therefore remain clearly visible as quality features in the long term.

conformity symbol h – The conformity symbol confirms that the apparatus fulfils the requirements of

the german weights and measures regulations as well as the relevant standards. This conformity with

Din 12 600 is printed directly on the glass.

Batch certificate – Volumetric flasks as well as measuring and mixing cylinders that are assigned to

accuracy class "A" and have a batch number come with a batch certificate. This certificate documents

the mean value derived from measuring the specified batch as well as the standard deviation and the

date of issue. The batch certificates are also available online.

The batch number comprises four digits, for example:

The first two digits indicate the batch and the second two digits indicate the year of production.

Individual certificate – Volumetric flasks that bear an individual number in addition to the batch number

come with an individual certificate. The individual number is lasered permanently onto the base of the

volumetric flask and entered on the associated certificate. Each volumetric flask is measured and test-

ed individually. This certificate documents the volume measured for the respective volumetric flask, the

uncertainty measurement and the date of issue. A batch certificate is also available as an option online.

The individual number is a consecutive number and comprises three letters and a four digit number,

for example: aaa-0001

USP individual certificate – The volumetric flasks are assigned an individual number. This number is

lasered permanently onto the base of the volumetric flask and entered on the associated certificate.

The accuracy limits for volumetric flasks that conform to USP <31> are stricter than for volumetric

flasks that conform to ISO 1042 and therefore fulfil the requirements contained in the United States

Pharmacopeia (USP). Each volumetric flask is measured and tested individually. This certificate

documents the volume measured for the respective volumetric flask, the measuring inaccuracy and

the date of issue.

precise reading made simple

The liquid at the edge of the vessel is

generally higher and therefore forms what

is known as the meniscus. The difficulty this

creates with reading can be avoided by

reading off at the lowest point of the liquid

surface. This means that the lowest point of

the meniscus should touch the top edge of

the measurement mark precisely.

Volumetric flasks can be marked permanently in the description field without damaging the glass. This

allows errors to be avoided when performing routine tasks. in addition, the vessels can be integrated

automatically into the complete workflow using a scanner, saving time and money.

The font size is predefined and the contents can be selected freely: markings can include barcodes,

serial numbers, texts, digits or logos. This is even possible regardless of the order quantity. The service

therefore applies equally to small and large batches.

DURan® polyeThylene sToppeR: exTRemely pRacTical solUTion

DURan® polyethylene stoppers are ergonomically shaped, therefore guaranteeing simple and secure

opening and closing of volumetric fl asks, mixing cylinders and reagent bottles. In addition, a cone with

several ring grooved fl anges ensures optimal leak tightness. Differently coloured stopper inserts ensure

simple and fast assignment of the ns size. The colour code is identical to that of the removable keck™

clips. Batch certifi cates for the DURAN® polyethylene stoppers are available at www.duran-group.com.

batch time: production details at a glance

The batch time located underneath every stopper comprises two concentric circles. The inner circle

indicates the year of production and also has an arrow pointing to one of the digits in the outer circle,

which indicates the month of production, for example a 1 for the month of January. The text "pe04"

can also be found on the underside of each stopper, which is the material designation for polyethylene.
